| (54) | Door leaf assembly with filling element of glass |
| (57) The present invention relates to the refinement of assembly structure of hubbed door
leaf installed with glass, which comprises a first door skin with an opening, a second
door skin with an opening, a top lacing material, a bottom lacing material, a left
lacing material, a right lacing material, a handle reinforcement member and the ejected
frame with multiplayer glass hold-down, wherein the door skin with opening can be
manufactured to be various shapes such as square, rectangular, circle, ellipse, and
semicircle depending on different mold. The characteristic is: When assembled, the
lacing materials are mounted to the edges of the first door skin by the adhesive.
The left and the right lacing materials are position-bonded, by ribs, to the flush-sided
door skin. The top and the bottom lacing materials are positioned through the milled
notchs at the top and the bottom ends of the left and the right lacing materials.
A reinforcement member is disposed at the handle position to enhance the mechanical
strength of the handle while locked. The openings of the two door skins have halving
structure to halve-joint together while assembled to form a closed cabin therebetween.
The bottom lacing material is then drilled with a hole through which the ammonium
polyester foaming plastic is filled into the cabin so as to finish the assembling
of the said door. |
Background of the Invention
Description of the prior art
[0001] In the prior art of door manufacturing, it is very common to cut an opening on the door and install glass to make change of the traditional door so as to meet the various needs of the market. However, problems are produced on the door manufacturing to achieve this goal:
1. The manufacturing efficiency is affected due to the necessity of increasing the processing of CNC center and the procedure of installing milling groove lacing materials to the four sides of the opening.
2. The waste from cutting the opening is wasted.
3. The prior halving glass assembling structure is not molded in one body , which causes less watertight and needs to be locked by screw and to be decorated by screw lid. The assembling process is much more complicated.
4. The prior halving structure door. which comprises two glass decorating frames, needs to be assembled and painted manually, which affects the efficiency.
5. The glass ejected-frame bulges out of the door skin. Consequently, the prior halving structure is unsuitable for a sliding door.
Brief description of the present invention
[0002] To solve the said problems of production efficiency, cost, waste disposal existing in the door manufacturing of prior art, the present invention discloses a refinement of R.O.C. New Model No. 107146 " Improvement of the Assembly Structure of the Hubbed Door ". More particularly, the present invention discloses a refinement of the assembly structure of hubbed door installed with glass.

Detailed Description of the Preferred Embodiments
[0005] The accompanying sheets of drawing allow us to appreciate the art contents of the present invention.
[0006] The present invention discloses an assembly structure of a hubbed door leaf installed with glass, which comprises two door leaf skins 1 and 2 with opening, a top and a bottom lacing materials 3, a left and a right lacing material 4, a handle reinforcement member 5, and a glass ejected-frame 6.
The said door skin 1 and 2 has a thickness of from about 1 MM to 4 MM; the four edges thereof are designed to be flush surface so as to be closely adhered to the top, the bottom. the left, and the right lacing materials 3 and 4 and then assembled. The said lacing material can be polyvinyl chloride foam profile, or wood, or steel, or ejected plastic. etc. The four edges of the opening of the door skin 1 are designed to be U shape structure 7 which are formed in one body. The four edges of the opening of the other door skin 2 are L shape structure 8 which are formed in one body; the rib 9 thereof inlays with the groove 10 of the U shape structure 7 when assembled in order to position. A space of about 0.5 by 2.3 MM is left between the rib 9 and the groove 10 after being assembled in order to prevent the overflow of the adhesive when assembled.
[0007] A horizontal rib 11 is provided at the external edge of the said U shape structure 7, which is utilized to support the multi-layer glass laid on the opening of the door. A groove 12 is provided at the surface of the rib, which can be spread with adhesive such as silicone before assembling the glass in order to closely bond the door and the glass so as to increase the function of watertight and gastight. The top of the U shape structure 11 is provided with two saw-shaped slopes 13 which form a horizontal groove with the external edge of L shape structure 8. The horizontal groove is provided to be inserted by the glass hold-down or the glass ejected-frame so as to fix the single layer or multi-layer glass.
[0008] The material of the said single layer or multi-layer glass ejected-frame can be wood, or steel, or polyvinyl chloride extrude profile, or PVC foam profile, or PVC plus wood scraps, or polystyrene, or polypropylene, or polypropylene plus fiber glass.
[0009] The material of the door skin 1 and 2 of the present invention can be the Sheet Molding Compound of reinforced fiber glass ( referring to R.O.C. Invention patent No. 69423), or wood fiber, or steel, or wood; the surface thereof can be a smooth surface without wood vein or be a mimetic wood vein. The depth of wood vein is about 0.05 to 0.2 MM. The opposite side of the said skin is a rough surface so as to increase the friction when the door is assembled by the adhesive.
[0010] The procedure of the assembly structure of hubbed door installed with glass is as follows ( please refer to Fig. 2 ):
Assembling the door skin 1 and 2, the top and the bottom lacing material 3 , and the left and the right lacing material 4 with adhesive. Then, dispose a reinforcement member 5 at the handle position to enhance the mechanical strength of the handle while locked. The openings of the two skins halve and assemble each other ( please refer to Fig. 3.) The adhesive can be used before halving in a practical example in order to increase its firmness. The left and the right lacing materials are position-bonded, by ribs, to the flush-sided door skin. The top and the bottom lacing materials are positioned through the milled notchs 4-3 ( please refer to Fig. 1 and Fig.2 ) at the top and the bottom ends of the left and the right lacing materials so as to form a closed cabin therebetween. The bottom lacing material is then drilled with a hole through which the ammonium polyester foaming plastic 21 is filled into the cabin so as to assemble the door ( please refer to Fig.4 and Fig.5.) Then, the glass is laid in and fixed by the hold-down or the glass ejected-frame 6.
[0011] To refine the overlaborate procedure. such as the necessity of processing by CNC center and of assembling the lacing material at the edges of opening, of the traditional hubbed door installed with glass, the present invention directly forms the edges of opening in one body during the manufacturing of the door skin and designs the edges of opening to be a halving structure to match the glass ejected-frame, wherein the advantages are:
1. Saving the cost of lacing material.
2. Decreasing the assembly labor by the halving assembly structure matching the glass ejected-frame.
3. Forming in one body so as to avoid the procedure of cutting the opening, whereby to decrease the production of waste and to obtain good water tight and air tight.
4. A reinforcement rib is designed at both the U shape structure and the glass ejected-frame structure to be strong enough to carry heavier load.
5. The dimension of glass opening is 22 inches by 36 inches which is most commonly used.
6. The maximum width of the door is 35.75 inches which can vary depending on various needs.
7. The bottom lacing material used in the swing door and window has two grooves so as to install the soft air tight lacing material much easier.
8. The bottom lacing material used in the swing door and window can be drilled the hole to install the roller.
